There are different types of mower filters. The most common are:
- Air filters:Clean the air going into the engine.
- Fuel filters:Remove dirt from the fuel before it reaches the engine.
- Oil filters:Clean the oil that lubricates engine parts.
Each filter has a special job. Air filters stop dust that can damage the engine. Fuel filters keep fuel clean for smooth running. Oil filters protect moving parts by removing dirt from oil.
